The present invention relates to visible indexes embodies, morespecifically, an improved portable type .of visible index by means ofwhich ,a plurality of interconnected sections may be utilized to supportthe desired indexing elements, the number, of sec; tions.andelements-carried by each being Val'lable at will. In applicantscopending application .fior .visible index, Serial No. 430,186 filedFebruary 21,, 1930., there :is described a visible indexby means ofwhich a plurality of index card supporting sections are vhinged togetherin the manner ,of the leaves of ,a book, the indexes being protected bysuch leaves and being ,readily moved to a suitable exposed position. ,orprotected position by opening or closing the said leav Theinterchangeability ,of: elements, together with the ability to increasethe capacity ,of the index, ,are features which will be readilyapparent. I

In the visible index describedand claimed herein, the structureincludes, basically, the features embodied the construction shown anddescribed in the above identified application and embodies,additionally, certain protective features which increase theserviceability and con enience of the i dex, as well as materiallyprotect the indexing (elements.

Accordingly, an object of the present invention is to p 0V 6 fivisible'index, the index=suppontingsections of which may bacon-=vieniently secured together in such manner that the sections may bereadily taken down ;or assembled to include a greater-0r a fewer numberof index-supportingsections.

.A funtherqobjeetof thei-nventienis to provide a means for preventingrelative movementrofzthe supporting sections towards each other beyond apredeterminedlimit to prevent marring 0f the index elements :duetosliding of portions thereof over :other portions. l

A iifiurtheraobject :of-the invention is to;pr0- avide an improved hingeconnection fabetween :the vcomponent :parts :of a visible index, .theconnection being of such character asato prevent lateral movement of onesection with 'a'espeot :to the ,other andrestra n ng the's aims :to"pivotal movement nnly.

Figure 7'is a viewsimilar to Figurefishowing the index ofFigure 5 Figure8 is ;a view in isometric projection showingaihinge member in detail. gReferring to the above drawings, a designates a tray which is-shown asbeing formed of metal although any other suitable ,substance may beemployed. As described in the above identified pending I application,this tray is provided with securing means 'or, by means of whichsuitable index elements, such-as cards a?,,may,be secured to thetrays.Inthe device shown in Figures 1,2,.and 3, two trays, as described above,'are utilized, being hinged togetheratanedge ofeachbya ,hinging' devicewhich will be-descnibed -more specifically hereinafter. If the ,trays,are,,95

formed. of metal,the top, bottomandpneside edge may be rolled to form ,asuitable head shaped portion of the member being formed with outwardlyextending portions 0, lying in the plane of the parallel portions of themember and terminating in pintle portions which lie perpendicular to theplane of the parallel arms of the U-shaped member. The

U-shaped portion 0 includes parallel arms 0 which serve as spacingmembers for the trays as described hereinafter. I

To assemble the device as shown in Figure 1, two trays a are secured atopposite ends by means of two hinge members a. o The pintles of thesemembers are inserted in the ends of the beads a andpressed inwardlyuntil the detents I) snap over the rounded shoulders formed by theportions 0. The trays are thus assembled in book form and may be openedor closed at will. In their closed position the trays are spacedpositively apart as clearly shown in Figure 8, by means of the parallelarms 0 Not only do these arms prevent the trays from rubbing againsteach other, but they also afford lateral stability against movement ofthe adjacent trays in their own planes, thus preventing lateral rubbingof the index elements carried by the respective trays. It will bereadily seen that movement of the upper tray, to the left, as viewed inFigure 3, in its own plane and parallel to the lower tray, will tend toforce the inwardly extending U-shaped portion 0 upwardly, or in acounterclockwise direction with respect to the beads a The extensionwill thus engage the upper tray and such movement will be preventedeffectively. Movement in the other direction will correvented fromcollapsing or rubbing together.

Where-it is desired that the index have additional capacity, two trays amay be secured back to back as by spot-welding to constitute a unit d asshown in Figure 7.

The beads a of the unit (Z are thus adapted to receive the hinge members0- 0f the outer trays a, all of the trays being prevented fromcontacting and rubbing by means of the hinges as described in connectionwith the construction shown in Figure 3.

K From the .foregoing, it will be seen that a visible index is provided,the elements ofwhich are completely standardized, each element beingsimple in construction and readily assembled with the cooperatingelements of the device and a standard form of hinge member beingapplicable to the standard form. of

"of the ends thereof and lying between the 'trays.

spondingly be prevented and the trays will h be held in parallelrelation and thus be pretray utilized. In addition to serving as aneffective hinging mechanism which is readily applied and taken down, thehinge members effectively stabilize the trays when the latter aremounted to form a visible index, either in theforms shown in Figures 1and 5, or in any form including added trays.

While the invention has been described with specific reference to theaccompanying drawings, it is not to be limited, save as de-. fined inthe appended claims.

I claim'as my invention 1. As an article of manufacture, a hinge memberhaving parallel pintles, inwardly extend-ingportions. at one ofthe endsthereof, and'a U-shaped offset portion connecting the inwardly extendingportions and lying in a plane at right-angles to the pintles.
